Maestro in action

Features

### Battle-tested, AI-native

Robust, open-source, time-tested - and now fully primed for human+AI development.

#### Close the agentic loop

Unlock high-velocity mobile development by powering up your agents with Maestro's AI toolkit.

#### Generate deterministic E2E tests

Maestro tests are human-readable YAML files, not black boxes. Repeatable, auditable, trustworthy.

Surfaces

### Build like the wind

Write and manage tests wherever you like, however fast you like.

#### Maestro MCP

Power up your favorite agent with our official MCP server. Give agents the "eyes and hands" to build and verify E2E coverage locally, fast and efficient, ensuring every change is fully tested before you ever open a PR.

#### Maestro Studio

Build tests in a visual IDE for Mac and Windows that makes manual test creation feel like magic. Contextual autocomplete, "tap-tap-tap" YAML generation, deep selector inspection, and an embedded emulator.

#### Maestro CLI

The lightweight, open-source engine for developers who prefer to bring their own IDE. Run human-readable YAML tests with the fastest, best runner in mobile - whether iterating locally or executing at scale in CI.
